2 Safety
2.1 Safety measures
●Only operate your product if all components are installed properly.
●Obey the local regulations on drinking water protection, accident prevention and
occupational safety.
●Do not make any changes, alterations, extensions or program changes on your
product.
●Only use genuine spare parts for maintenance or repair.
●Observe the maintenance intervals (refer to chapter 8.2). Failure to comply can
result in microbiological contamination of your drinking water system.
2.1.1 Danger due to carbon dioxide (CO2gas)
●The CO2gas is a non-combustible, non-corrosive, colourless and odourless gas
that is non-hazardous to water.
●It is one and a half times heavier than air and might accumulate close to the floor
or in low-lying parts of a building when released. CO2gas is classified as inert
(under normal conditions, no chemical reaction with other substances).
●Elevated CO2concentrations can occur in case of larger accumulations in enclosed
spaces.
●Higher CO2concentrations lead to health problems, even despite sufficient oxygen
levels, and there is a risk of asphyxiation.
2.1.2 Mechanical dangers
●You must never remove, bridge, or otherwise tamper with safety equipment.
●For all work on the device that cannot be carried out from the ground, use stable,
safe and self-standing climbing aids.
●Make sure that the device is set up in a way that it cannot tip over and that the
stability of the device is guaranteed at all times.
2.1.3 Pressure-related hazards
●Components can be under pressure. There is a risk of injuries and damage to
property due to escaping water and unexpected movement of components. Check
the pressure lines for leaks at regular intervals.
●Components of the device are pressurised. Do not loosen or remove components
which are under operating pressure.
●Before starting repair and maintenance work, make sure that all affected
components are depressurised.

Safety

2.1.4 Electrical dangers
There is an immediate danger of fatal injury from electric shock when touching live
components. Damage to the insulation or individual components can be life-threatening.
●Only have qualified electricians carry out electrical work on the device.
●In case of damage to live components, switch off the voltage supply immediately
and arrange for repair.
●Switch off the voltage supply before working on electrical system components.
Discharge the residual voltage.
●Never bypass electrical fuses. Do not put fuses out of operation. Observe the
correct current rating when replacing fuses.
●Keep moisture away from live parts. Moisture can cause short-circuiting.
●Do not open the device, you may come into contact with live parts.
2.1.5 Group of persons requiring protection
●Children must not play with the product.
●This product can be used by children over 8 years of age and persons with limited
abilities or lack of experience if they are supervised or instructed in the safe use of
the product and understand the resulting hazards.
●Cleaning and maintenance must not be carried out by children.
2.2 Product-specific safety instructions
2.2.1 Water supply
●The device is connected to the water supply system by means of removable hose
kits.
•Only use the hose kit included in the scope of delivery.
•Replace old, damaged hose kits - old hose kits must not be reused.
2.2.2 Power supply
●Portable multiple sockets or power supply units must not be placed at the back of
the device.
●The socket must not be located below the cold water connection.
●The plug must be fitted in such a way that the device can be unplugged
immediately and at all times in the event of malfunctions or maintenance work.
●Make sure that the socket has a protective earth conductor. Otherwise, retrofit the
socket with an adapter with protective earth contact.

Safety
10 | 72
BA_100182240000_en_074_SODA JET Office.docx
●The mains cable of the device must be laid free of kinks and tension.
●Do not wind up or squeeze the mains cable of the device.
●A damaged mains cable on the device must be replaced by the manufacturer, or
their after-sales service, or a similarly skilled person in order to avoid hazards.
2.2.3 Minimum distance between the back of the device and the wall surface
●The back of the device must be installed at a minimum distance of 50 mm from the
wall surface.
•The aeration and ventilation openings on the back of the device must be kept
clear.
•The minimum distance ensures the required air exchange rate for cooling the
cooling unit.
2.2.4 Danger from coolant in the cooling unit
●After transport in horizontal position, store the device in an upright position for at
least 24 h before starting it up.
●During transport, the oil contained in the compressor may shift in the cooling
system.
•After setting up the device, wait at least 1 hour before starting it up.
●The device should not be tilted when moving it.
●Do not put the device back into operation if it is damaged (e.g. if it falls over) -
danger due to flammable coolant.
•Contact customer service.
•The coolant R290 has flammability class A3 and must be disposed of by
qualified specialists for coolants only.

2.2.5 Handling CO2cylinders (compressed gas cylinders)
The installation of compressed gas cylinders must be carried out by qualified specialists
only.
The safety instructions and requirements for the operation of compressed gas cylinders
must be strictly adhered to.
DANGER
Risk of explosion

valve.
►Regularly check the connections for leaks and damage.
DANGER
Risk of asphyxiation from carbon dioxide (CO2)
●In case of damage, gas can escape.
►Check that the prerequisites below are fulfilled:
•The installation site must be suitable for the CO2gas cylinder used.
•Alternatively, a monitored technical ventilation system must exist.
•If this is not possible, a gas warning system for CO2/lack of oxygen must be
installed to protect the installation room.
Prerequisites when handling compressed gas cylinders
●When connected, store compressed gas cylinders in an upright position only and
secure them with the mounting bracket. Do not throw or tilt compressed gas
cylinders.
●Store compressed gas cylinders in a cool, well-ventilated place.
●Protect compressed gas cylinders from heat and direct sunlight.
●Keep them at a minimum distance of 500 mm to radiators other heat sources.

3.3 Functional description
The drinking water dispenser is connected to the cold water network of the domestic drinking
water system. In a cooling unit, the incoming drinking water is cooled to the desired
temperature.
The drinking water dispenser is designed for a dispensing capacity of up to 90 l/h in cycle
mode.
For the water types CLASSIC and MEDIUM the drinking water dispenser can be
continuously tapped for 5 minutes (1.5 l/min = 7.5 l).
●Cycle mode: max. 5 minutes continuous dispensing ► min. 10 minutes operational
break
In the STILL water path, the water is only cooled. Continuous tapping is possible.
In the CLASSIC water path, the water flows through a carbonator. The water in the
carbonator is enriched with food carbon dioxide (CO2) using an external CO2cylinder.
In the MEDIUM water path, still water and water containing CO2gas are mixed.
The solubility of the CO2is determined by the set operating parameters. The CO2
concentration depends on the water pressure, the CO2pressure and the temperature.
With a temperature controller on the back of the device, the cooling temperature can be
continuously adjusted between 5°C and 20°C.
Three different water types can be dispensed:
●STILL (refrigerated water)
●MEDIUM (cool and slightly sparkling)
●CLASSIC (cool and highly sparkling)
Depending on which dispense button is being pressed, the corresponding solenoid valves of
the dispenser unit open during tapping.
Any dripping water is collected in a built-in dripping water pan with filling level contacts, or
drained off via an optional drain connection.
If the dripping water pan is full, or not in the device, a fault signal is given by the MEDIUM
LED flashing.
SODA JET Office with flushing unit (optional)
This flushes the content of the device to the drain at regular intervals. Stagnation times are
reduced, and hygiene is improved. The drain connection is an essential requirement for this
purpose.
